Does anyone know how to replace the serpentine belt or the one for the water pump on a 2004 Taurus with a Duratec DOHC engine? There seems to be no way to adjust anything on the water pump, so how do you replace the belt, pull the water pump? For the serpentine belt you can't get to the tensioner. Do you need a special tool? Any help would be appreciated.

I spent almost 4 hours yesterday trying to fit a box wrench between the body of car and tensioner, and failed.

BTW I have a 24V DOHC Duratec 2001 Taurus, similar configuration as yours as far as belt is concern. Finally got some help from people at Autozone (via their ALLDATA.COM website). I am going to attempt to replace the belt tomorrow as per their instructions. Here is what they recommended:

I had to have my idler pulley replaced, under warranty. The mechanic had a tool specific for the job. It has a long handle and is very thin. Piece of cake to change the belt with this tool. Would probably be handy to have one if you work on your own vehicle.

The tool you're referring to is aptly called a "Serpentine Belt puller". It's basically a thin bar and half height sockets. I bought a kit from the local auto parts store. It came with 2 different bars, 3 metric sockets and 3 crows feet.

As I recall the kit cost about $20. Well worth case as I've changed about 5 serpentine belts with it, and can change a belt in less time than driving to the garage.
